Background

In Finland where the temperature can drop as low as -50°C in late winter, keeping wind turbines moving and generating energy can be a challenge. The formation of ice on the turbine blades impedes turbine efficiency and thrown ice presents a safety risk for surrounding people and property. By implementing comprehensive ice protection solutions, a wind farm can maximize energy production while mitigating these challenges.

Problem: 10% Loss of Annual Energy Production (AEP)

For a wind farm in Finland with Icing Class 3 conditions (Figure 1), ice accumulation on turbine blades can result in a 10% loss in annual energy production (AEP). For a 5.6 MW turbine operating at a 40% capacity factor, this equates to a significant annual revenue loss. Generic solutions like cold weather packages or blade coatings often fail to address severe icing, leading to costly downtime and potential safety risks from ice throw.

Solution: Comprehensive Ice Protection

The BorealisWind Ice Protection System (IPS) is a comprehensive solution that uses advanced meteorological sensors to detect icing conditions early and activate the blade heating system, effectively preventing ice formation and ensuring continuous turbine operation in harsh winter conditions.

Results = 91% Return on Investment

Within the first year of installing the IPS, a wind farm in Finland could earn a return on investment of 91%!

By effectively mitigating an estimated 70% of icing-related AEP losses, the wind farm could earn an additional $137,357 in revenue per turbine. With no capital expenses or maintenance costs to consider the IPS can mitigate icing-related AEP losses and increase revenue within the first year of installation.
